Nutrition is not one-size-fits-all. Nutrition, or the foods we eat, can help prevent and fight conditions such as high blood pressure, diabetes, stroke, and more.

Additionally, everyone breaks down food differently. Join the Nutrition for Precision Health research study to help researchers learn how our genes, cultural backgrounds, and environments affect our bodies' responses to food. Compensation provided.

During puberty, adolescents grow and change a lot which may make life seem more stressful and emotional. Male and female adolescents experience the changes associated with puberty differently, possibly because of different responses to changes in hormones, including testosterone and estrogen. We are interested in learning more about the role of these hormones in regulating emotional processing and mood symptoms, and whether a mobile training program can help improve mood during the pubertal transition. Participation is 8 weeks with two monthly follow-up surveys. Compensation provided.
